Definitions

  • the present invention relates to a solenoid switch for completing a main circuit of a starter motor and for moving a drive pinion of the starter motor outwards to engage in a ring gear on an engine flywheel.
  • the present invention also relates to a starter motor comprising such a solenoid switch.
  • An engine of a motor vehicle is normally started by an electric starter motor.
  • the starter motor drives the engine of the motor vehicle to operate at a high speed until the engine can operate independently and generate its own power output.
  • the starter motor consists of a direct current (DC) motor, a transmission mechanism and a control mechanism.
  • the DC motor obtains its electrical power supply from a battery and generates a rotary torque.
  • an ignition switch is switched on, a drive shaft of the DC motor is rotated and thus a crankshaft of the engine is driven to rotate.
  • the engine is started by the engagement of a drive pinion provided on the drive shaft of the DC motor with a ring gear on a flywheel of the engine.
  • the transmission mechanism of the starter motor is coupled to the drive shaft of the DC motor. After the engine is started, the transmission mechanism disengages the pinion from the ring gear to prevent the DC motor from being operated at excessive speeds.
  • a solenoid switch of the starter motor performs two functions: to move the drive pinion outwards to engage in the engine's ring gear; and to complete the main circuit of the DC motor.
  • the solenoid switch can be subjected to high loads and thus is widely used.

In this way, the engine is started.
  • the movable core 106 should rapidly return to its resting position (at the left side of Fig. 2) by the opposite magnetic force of the coil and by return springs 104 and 105, such that the pinion of the starter motor is disengaged from the ring gear.
  • the contact member 103 should be brought out of contact with the end faces of the electrical terminals 108 under the action of a return spring 101, so that the main circuit of the starter motor is disconnected and the starter motor is switched off.
  • the contact member 103 can not be brought out of contact with the end faces of the electrical terminals 108, since the pushing shaft 102 is relatively light and the spring force of the return spring 101 exerted on the pushing shaft 102 is relatively small. In this way, material adhesion or contact welding will occur between the contact member 103 and the electrical terminals 108. Further, if the contact member 103 and the electrical terminals 108 are welded together, an electrical current of up to 1500-2500A will flow through the solenoid switch 100 which will result in the burn-out of the solenoid switch 100.
